desirable material properties are the consequence of these factors hence they ought to be considered for the sake of sustainability of structures. Since this was a one-time boom, long term factors were not taken into consideration. The rules of the competition were to construct a boom that extended at least 1.5 meters horizontally from the front edge of the anchorage, touched nothing but the anchorage and was anchored in less than two minutes. The basic unweighted ratio for the competition was: However, the determination of the winning design was based on the following: Under the formula, the best boom finished with the highest ratio and the highest ratio would finish best in the EG1003 competition. In order to win, a team ought to maximize its ratio. With the boom weight and anchor time as denominators, the boom was to be as light as possible and anchored within the shortest possible time. In order to further maximize the ratio, the boom was to be much longer than 1.5m and carry more load than its weight with minimum deflection from its original height when loaded. The maximum deflection allowed by the TAs was 20cm from the boom’s original height. Procedure: Two thick dowels (1.1cm by 122cm), two thin dowels (0.8cm by 122cm), six bamboo skewers (30.5cm), 3D printed dowel connectors, cellophane tape and Kevlar string were used to construct the boom. Saws were also provided to cut the dowels, but these were used by TAs only. The EG 1003 C2 section was divided into four teams of three and one team of two. Materials provided were assessed and design options were considered by teams with competition specification in mind. Preliminary sketches were made during this period. Next, sketches of actual basic designs were made in pencil using paper provided by TAs. These designs were clearly labelled and handed over to TAs who signed and dated them. This was a sign of approval and teams who had this were free to begin their construction. First, the six bamboo skewers were secured together using a 3D connector. Next, a 15cm piece was cut off one of the thick dowels and the rest of the thick dowels were connected via a 3D connector resulting in approximately a 228cm length. This was inserted horizontally into the anchorage. The two thin dowels were positioned vertically in the upper anchor points and tied together at the top using Kevlar string. The 15cm piece was inserted horizontally into back of the anchorage to serve as opposition to downward deflection. The secured skewers were fitted
into one of the upper anchors point beside one of thin dowels to increase its stability. String was
